STOVE FOR CARS, STEAMBOATS, &.c.

SPECIFICATION forming part of Letters Patent No. 394,795, dated December18, 1888.

Application filed March 31, 1888. Serial No. 269,069. (No model.)

To all whom it may concern.-

Be it known that I, MATTHEW L. TEAFF, a citizen of the United States,residing at Dennison, in the county of Tuscarawas and State of Ohio,have invented certain new and useful Improvements in Stoves for Cars,Steamboats, .&c. and I do declare the following to be a full, clear, andexact description of the invent-ion, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

This invention relates to safety or fire-proof stoves, or, more properlyspeaking, a safe or case for a stove for railroad-cars, steamboats, andfor conveyances generally, of whatever nature, that are required tobeheated and which are likely to be overturned and upset the stove andspill the hot coals.

The object of the invention is the provision of a safe or case toreceive the stove, and which, in the event of accident, willautomatically close every inlet and outlet thereto and absolutely cutoff every avenue to the escape of hot coals, thereby preventing firebeing communicated to the car or other conveyance, which is oftentimesmore fatal in its consequences than the accident to the said car orconveyance itself. This case not only serves as an envelope for thestove, but forms a hotair chamber from which heated air may be conveyedto different parts of the apartment in which it is placed, or to otherapartments. The case will be made entirely of metal, plate steel,malleable and homogeneous, being best adapted for the purpose because ofits flexible and tenacious nature. These plates will be bolted togetherin any desired manner, and the case will be appropriately finished andornamel'lted to give it a pleasing an dimposing appearance.

The improvement consists of thenovel features which hereinafter will bemore fully described, and particularlypointed out in the claims, andshown in the annexed drawings, in which Figure 1 is a front view of astove or case embodying my invention; Fig. 2, a side view, parts beingbroken away, of the stove or case; Fig. 3, a detail side view showingthe hot-airpipe cut-off and the means for locking and operating it; Fig.4, a horizontal section on the line X X of 2; Fig. 5, a vertical sectionon the line Y Y of Fig. 3; Fig. 6, a top plan view of the case, the capbeing removed;

Fig. 7 a bottom plan view of the case; Fig. 8, asectional detail of thebottom of the case, showing the spring-catch for holding the door closedagainst the bottom of the case; and Fig. 9, a detail section on the line2 2 of Fig. 6.

The case A, which may be of any suitable outline in cross-section, iscomposed of the sides A, A A and A the top A and the bottom A and issupported above the floor, preferably on the feet A".

The stove B, of desired pattern, is placed within the case, the stoveand case being so proportioned that ample space is left between thestove and the case to permit the sides of the case from becoming heatedto such an extent that it would scorch a fabric placed against it. Thestovepipe 1) extends through an opening in the top of the case andthrough coincident openings in the guide-plate G, the cutting-plates O Cand the cap C and is provided with the heating-drum b, which iscylindrical and has corrugated heat-radiating ends b The plates formingthe sides of the case have their edges flanged and securely bolted orriveted together, and are re-enforced at the corners by the angle-ironsa.

The top and bottom are bolted to the top and bottom flanges of theplates.

The plate A is constructed to slide to place from above, being leftunbolted to permit the stove being placed in position. 'When the stoveis in place, the side A is adjusted and bolted. This side is providedwith the two doors a and (1 through which access is had to the fire-potand ash-pit-of the stove. These doors are securely locked at all timesexcept when the stove is receiving attention.

The bottom A is perforated to admit air to the stove and to the interiorof the case, and is provided with the door D, which is adapt-ed to closethe openings in the bottom. The springs E, secured at one end to thebottom A and having their free ends bearing 011 the lateral arms (Z ofthe door D, exert a pressure to force the said door shut when it isreleased, being normally held open by the hook d,

which engages a staple or eyelet in the floor. The brackets e, securedto the bottom A, limit the downward movement of the door. The doublespring-catch 6, depending from the bottom A, locks the door I) whenclosed.

The hot-air pipe F connects with the chest F, that is secured to a sideof the case, and the cut-oft F that works through the case, has anopening to register with the openings in the side of the chest and (r;This cutot'f is forced up by anymeans to shut otli' communicationbetween the hot-air pipe and the chest, preferably by the spring f,mounted on the pull-rodf and held between the bottom A and the arm f*.The arm f is apertured to permit the passage of the pull-rod f, and itsouter end passes through the cut-ell. The lower end of the pull-rod.extends through the bottom A and is fastened to the door by the hook f.The upper end of the cut-oft is beveled to form the arrow-shaped head fwith notches f in its edges, in which the ends of the doublespring-clutch G tit: and hold the cut-ott up when closed.

The guide-plate (.1 has cross grooves or channels, in which thecutting-plates t) and are fitted and work, the edges of the channelsbeing undercut to receive the edges of the cutting-plates. The ends ofthe cuttingplates project beyond the sides of the case a suitabledistance and have stops formed by thickening the ends of the plates,which pre vent the plates from slipping out endwise. The openings in theplates 0 and (1 have their edges beveled to a knife-edge, so that theywill readily sever the pipe in the event of the stove toppling over orbeing struck a smart blow.

The springf is protected by thelujnisingll, and is located within thecase, so as to be out of the way. 7

'When the stove is adjusted in the desired position, it is held by anysuitable t'astenin devices or means to prevent it shifting. The pull-rodf is held down by the hook f", driven in the floor, and the link Thedoor I) is held open against the tension of the springs E by the link(1' and the eyelet d driven in the floor. In the event 01: an accidentsuitieient to dislodge the stove, the fastenin between the pull-rod andthe floor and between the door D and the .iioor will be broken and thecut-off will close the hot-air opening, and the door 1) will close theopenings in the said bottom, each being operated and locked by the meanshereinbefore described. It the stove should overturn or strike the sideof the ve hicle or conveyance, the cutting-plates, having their endsprojecting beyond the sides of: the stove,wil1 be the first to strike,and, moving in, will sever the pipe. The cutting-plate is limited in itsinward movement by the stop hereinbefore mentioned, and is pre ventedfrom moving out by coming in. con

tact with the object against which it first i mpacted, and which terms asupport for the stove.

Having thus described my invention, what I claiin, and desire to secureby lietttn's Pat.- ent, is-- 1. The combination, with theherein-described sat'e or case for a stove, having a smoke-pipe, of acutting-plate to sever the smoke-pipe and close the opening throughwhich the said smoke-pipe projects, substantially as described.
